Title: Adding Identity, Claim and proof

There are many cases in social systems where third party identities are associated with the main identity (e.g. linking facebook and twitter accounts to a user account). Unfortunately, there are no existing common models or standards to draw on in terms of how these are represented after the fact. Introducing Identity, Claim and proof provide a way.

```json
{
"@type": "Claim",
"actor": "acct:sally@example.org",
"object": {
"@type": "Identity",
"@id": "acct:sally@example.net"
},
"proof": {
"@type": "...",
"@value": "..."
}
}
```
